STM32L4R9-Discovery and external PSRAM
Hello,I am currently working with a STM32L4R9-Discovery board with STemWin using demonstration project.I want to use the external PSRAM as a memory for the LCD GFXMMU framebufferfrom LCDConf.c :#if defined ( __ICCARM__ ) #pragma location="FrameBuffer...
SystemClock_Config() crashing on discovery
Hi everyone,SystemClock_Config() works on Nucleo-144 board but not on Discovery even though they both have a F746 mcu on them.
STM32F030 IS NOT PROGRAMMING SUCCESSFULLY
Hi, we are using STM32f030 micro controller for our tracking device design. We have programmed some boards successfully using STM32 debugger. But in one board we are unable to program the code. there are some data saving to the controller memory whil...
Writing Blocks of ADC DMA Conversions to SD Card on the STM32F7 Discovery Board (ADC + Timer + DMA + SDMMC)
I'm trying to write blocks of ADC Conversions using DMA from the STM32F46 Dsicovery board and I'm having issues writing to the SD card when HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef* hadc) is called. I'm running a 500KHz timer to trigger my ADC and ...
Communication between stm32l476rc and fuel gauge(bq40z50r2) through I2C.
Hello sir, i am trying to send command to fuel gauge from stm32l476 to get data like voltage,current and temperature of battery but not getting sir.Even sda or scl line unable to see on oscilloscope. i written a code for i2c but not working .please ...
Resolved! pwm with asymmetric dead-time
I am looking into the possibility of using a stm32 microcontroller (probably stm32f030) to directly* control the power transistors in a switch-mode power supply, in order to generate a high-power waveform.My current thinking has a PMOS switch transis...
Resolved! STM32F030R8T6 Timer 3 Initialization Problem
Greetings Everybody,I am initializing STM32F030R8 Timer 3 with 48MHz clock and pre scaller 480 - 1 -> 479 and counter period 1. Technically this timer 3 interrupt should be generated at 48MHz / 480 -> 100KHz. On every interrupt i am toggling PA4 GPIO...
Problem with HAL_FLASH_OB_Launch, STM32H7 swapping flash banks
Ok just trying to get the bank swapping working.Loaded and flashed new firmware in to 0x08100000 all goes fine, all i need to do is to swap the flash banks.Now the code below does do the bank swap fine, but it gets stuck at the HAL_FLASH_OB_Launch();...
How to run I2C communication between STM32L476RC controller and BQ40Z50R2?
I am trying to do I2C communication between STM32L476RC and Fuel gauge IC(BQ40Z50R2),for that i am using following components: 1) STM32L476RC Controller 2) BQ40Z50R2 Fuel gauge IC 3) STM32 CubeMx software 4) Keil softwareThe datasheet...
